Police arrest 17-year-old in deadly mass shooting at California mall

( KTLA ) – A 17-year-old boy has been arrested in connection with a mass shooting at a Spirit Halloween store in Northern California that left a pregnant woman dead and six other people injured, authorities announced Monday.

The suspect was arrested Nov. 2 at a home in Suisun City, three days after the deadly shooting at the Solano Town Center mall in Fairfield, according to the Fairfield Police Department .

The teenager, whose identity has not been released because of his age, was booked on suspicion of murder and attempted murder.

Pregnant woman killed, six others wounded at Halloween store

The Oct. 30 shooting occurred around 8:30 p.m. at the Spirit Halloween store located at 1350 Travis Blvd., where shoppers were purchasing last-minute costumes ahead of Halloween.

Officers responded to reports of gunfire and found seven people suffering from gunshot wounds.

Investigators said the shooter entered the store, spotted someone believed to be the intended target and opened fire, striking that person and six others.

The suspect fled the scene before officers arrived.

Authorities identified the woman killed as 31-year-old Constance Hages, who was pregnant, according to information provided by her family.

According to the San Francisco Chronicle , police believe Hages was the intended target of the shooting, which may have stemmed from an earlier disagreement. However, no information was provided on how the teen and the victim may know each other or what their relationship may have been.

Six other victims, all males between the ages of 16 and 43, were transported to hospitals.

As of Monday, four remained hospitalized, including a 19-year-old man in critical condition. Three others, ages 16, 23 and 32, were listed in stable condition.

Two additional victims, ages 19 and 43, were treated and released.

Teen suspect arrested following investigation

Detectives identified the alleged gunman within hours of the shooting after reviewing surveillance footage from inside the Halloween store.

A school resource officer recognized the teenager as a former student, helping investigators establish his identity, the Chronicle reported.

On Monday, police located the suspect in Suisun City and took him into custody.

During a news conference, Fairfield Police Chief Dan Marshall revealed that the teenager had previously been involved in a shooting at Fairfield High School in 2025.

According to police, the suspect was charged in that case and spent several months in juvenile detention before being released.

“This event shouldn’t have even occurred,” Marshall said, criticizing California’s handling of juvenile offenders.

Marshall called for changes to California’s juvenile justice system in the wake of the deadly attack, Bay City News Service reported .

The suspect is believed to have acted alone, though investigators are examining whether anyone else may have been involved.

The Solano County District Attorney’s Office is reviewing the case, including whether Hages’ pregnancy could warrant an additional murder charge. Formal charging decisions had not been announced as of Monday evening.

The investigation remains ongoing, with assistance from the FBI, officials said.
